- Aim: The aim of this study was to explore the thinking strategies and clinical reasoning processes registered nurses use during simulated care planning for malnutrition and pressure ulcers in nursing home care.Background: Clinical reasoning is an essential component of nursing practice. Registered nurses’ thinking strategies and clinical reasoning have received limited attention in nursing science. Further research is needed to understand registered nurses’ clinical reasoning, especially for prevention of malnutrition and pressure ulcers as they are important quality indicators of resident care in nursing homes.Design: A qualitative explorative design was used with a think-aloud interview technique.Methods: The transcribed verbalisations were analysed with qualitative deductive content analysis. Data were collected during six months in 2007-2008 from 30 registered nurses at nine nursing homes in Norway.Results: The registered nurses used a variety of thinking strategies, but there were differences in the frequency of use of the different strategies. The three most commonly used thinking strategies were ‘making choices’, ‘forming relationships’ and ‘drawing conclusions’. None of the nurses performed a structured risk assessment of malnutrition or pressure ulcers. Registered nurses started with assessing data from the scenarios, but after a short and elementary assessment they moved directly to planning.Conclusion: Many different thinking strategies were used in registered nurses’ clinical reasoning for prevention of malnutrition and pressure ulcers. The thinking strategy ‘making choices’ was most commonly used and registered nurses’ main focus in their reasoning was on planning nursing interventions. Relevance to clinical practice. This study showed that most of the registered nurses go directly to planning when reasoning clinically about residents in nursing homes. A lack of systematic risk assessments was identified. The insight gained from this study can be used to recommend improvements in tools designed for nursing homes to support the registered nurses.

- Initiation factor (IF) 2 controls the fidelity of translation initiation by selectively increasing the rate of 50S ribosomal subunit joining to 30S initiation complexes (ICs) that carry an N-formyl-methionyl-tRNA (fMet-tRNA(fMet)). Previous studies suggest that rapid 50S subunit joining involves a GTP- and fMet-tRNA(fMet)-dependent "activation" of IF2, but a lack of data on the structure and conformational dynamics of 30S IC-bound IF2 has precluded a mechanistic understanding of this process. Here, using an IF2-tRNA single-molecule fluorescence resonance energy transfer signal, we directly observe the conformational switch that is associated with IF2 activation within 30S ICs that lack IF3. Based on these results, we propose a model of IF2 activation that reveals how GTP, fMet-tRNA(fMet), and specific structural elements of IF2 drive and regulate this conformational switch. Notably, we find that domain III of IF2 plays a pivotal, allosteric, role in IF2 activation, suggesting that this domain can be targeted for the development of novel antibiotics.

- Qualitative research has made a significant contribution to the body of knowledge related to how people experience living with various chronic diseases and disabilities, however, the voices of certain vulnerable populations, particularly those with impairments that affect their ability to communicate, are commonly absent. In recent years, a few researchers have attempted to explore the most effective ways to ensure that the voices of people with communication impairments from acquired brain damages can be captured in qualitative research interviews, yet several methodological issues related to including this population in qualitative research remained unexamined. In this article, the authors draw on insights derived from their research on the experiences of adult survivors of stroke and traumatic brain injury to describe methodological issues related to sampling, informed consent, and fatigue in participant and researcher while also making some recommendations for conducting qualitative interviews with these populations.
